Cervical teratoma is a rare congenital tumor that tends to be large and is usually solid/cystic. Estimation of the degree of tracheal compression or distortion allows multidisciplinary planning for delivery and neonatal resuscitation. We present a case of prenatal diagnosis of cervical teratoma at 29 weeks of gestation. The use of a physical model from 3D ultrasound and magnetic resonance imaging improved the understanding of spatial relationships of fetal anomaly and the adjacent structures, permitting better parent counselling. This technology can be used for educational purposes and as a method for parents to visualize their unborn baby.

Abstract A 26-year-old woman was treated for a prolactin secreting pituitary adenoma by surgery and radiotherapy (5860 rads). Fourteen months later, she developed right hemiparesis and dysarthria. A T1-weighted magnetic resonance imaging scan using gadolinium contrast showed a small, enhanced lesion in the upper pons. Seven months later, she had a sudden onset of loss of vision, and radiation optic neuropathy was diagnosed. A T1-weighted magnetic resonance imaging scan showed widespread gadolinium-enhanced lesions in the optic chiasm, optic tract, and hypothalamus. Magnetic resonance imaging is indispensable for the early diagnosis of radiation necrosis, which is not visualized by radiography or computed tomography.

Abstract Three cases of a mobile cauda equina schwannoma, preoperatively diagnosed by magnetic resonance imaging, are described. When dealing with tumors of the cauda equina, it is important to carry out a second magnetic resonance imaging scan after changes in posture, bearing in mind the possibility of mobility of the tumor.

A 75-year-old gentleman presented to our department with dysphagia, nocturnal cough and dysphonia. Clinical examination revealed a large parapharyngeal mass extending from the left nasopharynx to the glottis. A magnetic resonance imaging scan confirmed the lipomatous nature of the lesion and elegantly demonstrated its anatomy. We discuss the aetiology and management of such lesions and focus on the diagnostic radiology of the parapharyngeal space.
